Synergism and Rules from Combination of Baicalin,Jasminoidin and Desoxycholic acid in Refined Qing Kai Ling for Treat Ischemic Stroke Mice Model

Refined Qing-Kai-Ling (QKL), a modified Chinese medicine, consists of three main ingredients (Baicalin, Jasminoidin and Desoxycholic acid), plays a synergistic effect on the treatment of the acute stage of ischemic stroke. However, the rules of the combination and synergism are still unknown. Based on the ischemic stroke mice model, all different kinds of combination of Baicalin, Jasminoidin, and Desoxycholic acid were investigated by the methods of neurological examination, microarray, and genomics analysis. As a result, it confirmed that the combination of three drugs offered a better therapeutical effect on ischemic stroke than monotherapy of each drug. Additionally, we used Ingenuity pathway Analysis (IPA) and principal component analysis (PCA) to extract the dominant information of expression changes in 373 ischemia-related genes. The results suggested that 5 principal components (PC1-5) could account for more than 95% energy in the gene data. Moreover, 3 clusters (PC1, PC2+PC5, and PC3+PC4) were addressed with cluster analysis. Furthermore, we matched PCs on the drug-target networks, the findings demonstrated that Baicalin related with PC1 that played the leading role in the combination; Jasminoidin related with PC2+PC5 that played a compensatory role; while Desoxycholic acid had the least performance alone which could relate with PC3+PC4 that played a compatible role. These manifestations were accorded with the principle of herbal formulae of Traditional Chinese Medicine (TCM), emperor-minister-adjuvant-courier. In conclusion, we firstly provided scientific evidence to the classic theory of TCM formulae, an initiating holistic viewpoint of combination therapy of TCM. This study also illustrated that PCA might be an applicable method to analyze the complicated data of drug combination.     

The Anticonvulsant and Neuroprotective Effects of Baicalin on Pilocarpine-Induced Epileptic Model in Rats

Baicalin, a flavonoid compound purified from plant Scutellaria baicalensis Georgi, has been reported to possess a wide variety of pharmacological properties including anti-oxidative, anti-apoptotic and neuroprotective properties. Oxidative stress can dramatically alter neuronal function and has been linked to status epilepticus (SE). However, the neuroprotective effect of baicalin on epilepsy is unclear. In this study we investigated whether Baicalin could exert anticonvulsant and neuroprotective effects in the pilocarpine-induced epileptic model in rats. To this end, we recorded the latency to first limbic seizure and SE and observed the incidence of SE and mortality. The changes of oxidative stress were measured 24 h after pilocarpine-induced SE. Nissl staining, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling and Fluoro-Jade B staining were performed to detect the neuronal loss, apoptosis and degeneration in hippocampus 72 h after pilocarpine-induced seizure. Pretreatment with baicalin significantly delayed the onset of the first limbic seizures and SE, reduced the mortality rate, and attenuated the changes in the levels of lipid peroxidation, nitrite content and reduced glutathione in the hippocampus of pilocarpine-treated rats. Furthermore, we also found that baicalin attenuated the neuronal cell loss, apoptosis, and degeneration caused by pilocarpine-induced seizures in rat hippocampus. Collectively, these results indicated remarkable anticonvulsant and neuroprotective effects of baicalin and should encourage further studies to investigate baicalin as an adjuvant in epilepsy both to prevent seizures and to protect against seizure induced brain injury.

Antioxidant, Anticonvulsive and Neuroprotective Effects of Dapsone and Phenobarbital Against Kainic Acid-Induced Damage in Rats

Excitotoxicity due to glutamate receptors (GluRs) overactivation is a leading mechanism of oxidative damage and neuronal death in various diseases. We have shown that dapsone (DDS) was able to reduce both neurotoxicity and seizures associated to the administration of kainic acid (KA), an agonist acting on AMPA/KA receptors (GluK1–GluK5). Recently, it has been shown that phenobarbital (PB) is also able to reduce epileptic activity evoked by that receptor. In the present study, we tested the antioxidative, anticonvulsive and neuroprotective effects of DDS and PB administered alone or in combination upon KA toxicity to rats. Results showed that KA increased lipid peroxidation and diminished reduced glutathione (GSH), 24 h after KA administration and both drugs in combination or individually inhibited these events. Likewise, KA promotes mortality and this event was antagonized by effect of both treatments. Additionally, the behavioral evaluation showed that DDS and PB administered alone or in combination decreased the number of limbic seizures and reduced the percentage of animals showing tonic–clonic seizures versus the control group, which was administered only with KA. Finally, our study demonstrated that all of the treatments prevented the neuronal death of the pyramidal cell layer of hippocampal CA-3. In conclusion, the treatment with DDS and PB administrated alone or in combination exerted antioxidant, anticonvulsive and neuroprotective effects against the neurotoxicity induced by KA in rats, but their effects were not additive. Thus, it may be good options of treatment in diseases such as epilepsy and status epilepicus, administered separately.     

Effects of Ethanol and Polychlorinated Biphenyls in Combination on Ascorbic Acid Metabolism,Liver Drug-metabolizing Enzymes,and Lipid Metabolism in Rats

We investigated the combined effects of ethanol and polychlorinated biphenyls (PCB) on ascorbic acid metabolism, liver drug-metabolizing enzymes, and lipid metabolism in rats fed on a diet containing by 36% by energy of ethanol and 0.005% of PCB, either singly or in combination, for 49 days. Ethanol and PCB given together synergistically affected the amount of ascorbic acid excreted in the urine and the serum concentration of ascorbic acid. This synergistic effect was also observed in the activity of aniline hydroxylase in the liver. Ethanol and PCB given together seem to have had different effects on lipid metabolism. These results suggest that the effect of ethanol on the metabolism of ascorbic acid and of drugs may be enhanced by combined administration with PCB, and that the ascrobic acid deficiency and/or modification of the drug metabolism may become more serious.     

Effects of Acupuncture on Glycometabolic Enzymes in Multi-infarct Dementia Rats

Acupuncture has exhibited therapeutic effects on vascular dementia in our previous research. The mechanism of its anti-dementia effects involves energy metabolism. For brain cells, glucose metabolism is almost the only source of energy, and glucose metabolism disorders are early signs of dementia. In addition, glucose metabolism associates closely with glycometabolic enzymes, thereby maintains normal energy supply in brains and neurological and mental activities. In order to investigate its anti-dementia mechanism, we studied the effects of acupuncture on behavior of multi-infarct dementia (MID) rats and glycometabolic enzymes protein expression and activities in their brains. Results showed acupuncture improved the cognitive disorder, and increased the activities of hexokinase, pyruvate kinase, and glucose 6 phosphate dehydrogenase. Accordingly, it suggests that the anti-dementia effects of acupuncture may be mediated by up regulation of hexokinase, pyruvate kinase, and glucose 6 phosphate dehydrogenase activities, influencing energy metabolic system and thus overcoming the dysfunctional cognition of MID.

Excitatory Amino Acid-Induced Toxicity in Chick Retina: Amino Acid Release, Histology, and Effects of Chloride Channel Blockers

Acute excitotoxicity in embryonic chick retina and the ability of Cl- channel blockers to prevent toxicity were evaluated by measurement of endogenous amino acid release and histology. Treatment of retina with kainate, quisqualate, or N-methyl-D-aspartate resulted in a large dose-dependent release of gamma-aminobutyric acid and taurine, moderate release of glutamine and alanine, and no measurable release of glutamate or aspartate. Concentrations inducing maximal gamma-aminobutyric acid release were 50 microM quisquaalate, 100 microM kainate, and 100 microM N-methyl-D-aspartate. Treatment with 1 mM glutamate resulted in significant gamma-aminobutyric acid release, as well as an elevation in medium aspartate levels. Typical excitotoxic retinal lesions were produced by the agonists and, at the lower concentrations tested, revealed a regional sensitivity. There was a positive correlation between the amount of gamma-aminobutyric acid release and the extent of tissue swelling, suggesting that release may be secondary to toxic cellular events. Omission of Cl- completely blocked cytotoxic effects due to kainate or glutamate. Likewise, addition of the Cl-/bicarbonate anion channel blocker 4,4'-diisothiocyanatostilbene-2,2'-disulfonate at 600 microM protected retina from cytotoxic damage from all excitotoxic analogs and restored amino acid levels to baseline values. Furosemide, which blocks Na+/K+/2Cl- cotransport, was only minimally effective in reducing amino acid release induced by the agonists. Consistent with the latter, histological examination showed the continued presence of the lesion but with general reduction of cellular edema. These results indicate that although influx of Cl- is a central component of the acute excitotoxic phenomenon, mechanisms other than passive Cl- flux may be involved.     

Superoxide Dismutase Activity During Dimethylhydrazine Colon Carcinogenesis and the Effects of Cholic Acid and Indole

Copper, zinc superoxide dismutase (Cu, ZnSOD) and manganese superoxide dismutase (MnSOD) activities were measured in mouse large intestinal mucosa during dimethylhydrazine (DMH) carcinogenesis. Mice were divided into five groups. Group A was subcutaneously injected with DMH (20mg/kg) weekly and fed with a diet containing 0.2% cholic acid (C) and 0.8% indole (I). Group B was injected with DMH and given indole feeding. Group C was treated with DMH injection and cholic acid feeding. Group D was given DMH injection alone. Group E was an age-matched control group given 0.9% NaCl injection. The experiment last 21 weeks. The Cu, ZnSOD activity of intestinal mucosa in group A animals began to increase significantly at the 7th week of the experiment. In groups B, C and D, however, this enzyme was not elevated statistically until the 16th week, and then each of these groups kept an increased Cu, ZnSOD level the rest of the experimental period. MnSOD activity was elevated statistically in group C animals at the 7th week. The enzyme activity in group A and D animals increased at the 9th week, but the enzyme activity did not increase statistically until the 11th week in group B. After the 16th week of the experiment the increased activity of MnSOD in all experimental groups returned to the level of the control group. Large intestinal cancer tissues had increased Cu, ZnSOD activity and decreased MnSOD activity.

Effects of a Cardiotonic Medicine,Danshen Pills,on Cognitive Ability and Expression of PSD-95 in a Vascular Dementia Rat Model

A widely used Chinese cardiotonic proprietary medicine, compound Danshen dripping pills (CDDP, Fufang Danshen Diwan) has also begun to be used for treatment of vascular dementia (VaD). We tried to explore the mechanism of CDDP action in this case. A VaD experimental model was built in rats by bilateral ligation of the common carotid arteries. The cognitive ability of experimental animals was evaluated in the Morris water maze test. Synaptic ultrastructural changes in the hippocampus were detected by transmission electron microscopy; expression of PSD-95 mRNA in the hippocampus was examined using hybridization in situ. The latter index (mRNA expression) in the VaD group was significantly lower than those in the CDDP and sham-operated groups (P < 0.05). CDDP treatment considerably improved disturbed ultrastructural synaptic characteristics in the hippocampus of VaD rats. The mean escape latency in the Morris water maze test was significantly shorter in CDDP-treated VaD rats, compared with that those of the VaD group (P < 0.05). In the CDDP group compared to the VaD one, escape strategies improved from edge and random searches to more linear swim pathway (P < 0.05). Thus, decreasing expression of PSD-95 plays an important role in the pathogenesis of VaD. CDDP treatment improves the learning and memory ability of VaD rats by improving neural synaptic ultrastructural characteristics and increasing expression of PSD-95 mRNA in the hippocampus.     

Cholic Acid Induces a Cftr Dependent Biliary Secretion and Liver Growth Response in Mice

The cause of Cystic fibrosis liver disease (CFLD), is unknown. It is well recognized that hepatic exposure to hydrophobic bile salts is associated with the development of liver disease. For this reason, we hypothesize that, CFTR dependent variations, in the hepatic handling of hydrophobic bile salts, are related to the development CFLD. To test our hypothesis we studied, in Cftr^-/- and control mice, bile production, bile composition and liver pathology, in normal feeding condition and during cholate exposure, either acute (intravenous) or chronic (three weeks via the diet). In Cftr^-/- and control mice the basal bile production was comparable. Intravenous taurocholate increased bile production to the same extent in Cftr^-/- and control mice. However, chronic cholate exposure increased the bile flow significantly less in Cftr^-/- mice than in controls, together with significantly higher biliary bile salt concentration in Cftr^-/- mice. Prolonged cholate exposure, however, did not induce CFLD like pathology in Cftr^-/- mice. Chronic cholate exposure did induce a significant increase in liver mass in controls that was absent in Cftr^-/- mice. Chronic cholate administration induces a cystic fibrosis-specific hepatobiliary phenotype, including changes in bile composition. These changes could not be associated with CFLD like pathological changes in CF mouse livers. However, chronic cholate administration induces liver growth in controls that is absent in Cftr^-/- mice. Our findings point to an impaired adaptive homeotrophic liver response to prolonged hydrophobic bile salt exposure in CF conditions.     

Ameliorative Effect of Chrysin on Adenine-Induced Chronic Kidney Disease in Rats

Chrysin (5, 7- dihydroxyflavone) is a flavonoid with several pharmacological properties that include antioxidant, anti-inflammatory and antiapoptotic activities. in this work, we investigated some effects of three graded oral doses of chrysin (10, 50 and 250 mg/kg) on kidney structure and function in rats with experimental chronic renal disease (CKD) induced by adenine (0.25% w/w in feed for 35 days), which is known to involve inflammation and oxidative stress. Using several indices in plasma, urine and kidney homogenates, adenine was found to impair kidney function as it lowered creatinine clearance and increased plasma concentrations of creatinine, urea, neutrophil gelatinase-associated lipocalin and N-Acetyl-beta-D-glucosaminidase activity. Furthermore, it raised plasma concentrations of the uremic toxin indoxyl sulfate, some inflammatory cytokines and urinary albumin concentration. Renal morphology was severely damaged and histopathological markers of inflammation and fibrosis were especially increased. In renal homogenates, antioxidant indices, including superoxide dismutase and catalase activities, total antioxidant capacity and reduced glutathione were all adversely affected. Most of these adenine – induced actions were moderately and dose -dependently mitigated by chrysin, especially at the highest dose. Chrysin did not cause any overt adverse effect on the treated rats. The results suggest that different doses of chrysin produce variable salutary effects against adenine-induced CKD in rats, and that, pending further pharmacological and toxicological studies, its usability as a possible ameliorative agent in human CKD should be considered.

Ameliorative Effects of Propolis and Royal Jelly against CCl4-Induced Hepatotoxicity and Nephrotoxicity in Wistar Rats

Carbon tetrachloride (CCl₄) is known to have hepatotoxic and nephrotoxic effects. During the two-month CCl₄ exposure of Wistar rats, propolis extract (PE) and royal jelly (RJ) were added in order to test the potential protective effect against hepato-renal injury. Ketonuria, proteinuria, high creatinine and urea levels are the result of CCl₄-induced nephrotoxicity. Severe disorders of hematological indicators indicate anemia; high values of leukocytes indicate inflammatory condition. Cytogenetic impairments in hepatocytes, aggregation of platelets, and hypoproteinemia indicate severe liver impairment. Results suggest a more significant protective role of RJ compared to PE. Both extracts regulated proteinuria, ketonuria, hypoproteinemia and reduced platelet aggregation in the hepatic circulation. The increase in the number of erythrocytes (RBC) suggest protective effects against anemia; the decrease in the number of leukocytes can be linked to anti-inflammatory effects. PE and RJ have a beneficial effect against hepato-renal injury, anemia and anti-inflammatory conditions caused by CCl₄.     

Neuroprotective Effects of Bacopa monnieri in Experimental Model of Dementia

Alzheimer disease (AD) is characterized by dementia that begins as mild short term memory deficit and culminates in total loss of cognitive and executive functions. The present study was conducted to evaluate the neuroprotective potential of Bacopa monnieri (BM), an Indian traditional medicinal plant effective against cognitive impairment, in colchicine-induced dementia. Intracerebroventricular administration of colchicine (15?μg/5?μl) induced cognitive impairment in rats as assessed by elevated plus maze. This was accompanied by a significant increase in oxidative stress in term of enhanced levels of lipid peroxidation and protein carbonyls. Concomitantly, decrease in activity of antioxidant enzymes was observed in colchicine treated animals. BM (50?mg/kg body weight) supplementation reversed memory impairment observed in the colchicine treated rats. BM administration attenuated oxidative damage, as evident by decreased LPO and protein carbonyl levels and restoration in activities of the antioxidant enzymes. The activity of membrane bound enzymes (Na(+)K(+) ATPase and AChE) was altered in colchicine treated brain regions and BM supplementation was able to restore the activity of enzymes to comparable values observed in controls. The results suggest therapeutic potential of BM in the treatment of AD associated cognitive decline.     

Protective Effects of Chlorogenic Acid on Paraquat-induced Oxidative Stress in Rats

The protective effects of chlorogenic acid on paraquat-induced oxidative stress were examined in rats. The activities of erythrocytes and liver glutathione peroxidase, and of both liver catalase and glutathione reductase, which were increased by feeding paraquat, declined to the levels in the control rats by supplementing chlorogenic acid to the paraquat diet. The activity of superoxide dismutase was not changed by dietary paraquat or by supplementing chlorogenic acid to the paraquat diet. Paraquat in the diet markedly decreased the liver triacylglycerol and phospholipid concentrations, as well as the food intake and body weight gain, while chlorogenic acid protected against these decreases. These in vivo results and the in vitro superoxide anion scavenging activity of chlorogenic acid suggest that chlorogenic acid acted preventively against paraquat-induced oxidative stress.
